Null geodesics and embedding diagrams of the interior Schwarzschild-de Sitter spacetimes with uniform density.
Null geodesics and embedding diagrams of central planes in the ordinary space geometry and the optical reference geometry of the interior Schwarzschild-de Sitter spacetimes with uniform density are studied. For completeness...

Helmholtz conditions in the geometry of second order ordinary differential equations
Helmholtz conditions (necessary and sufficient conditions of existence of a Lagrangian for a system of second order ordinary differential equations) carry a lot of geometric information about variational equations. Some of the important resu...

Palatini variation in generalized geometry and string effective actions
We develop the Palatini formalism within the framework of generalized Riemannian geometry of Courant algebroids. In this context, the Palatini variation of a generalized Einstein-Hilbert-Palatini action -formed using a generalized metric, a ...
